US Open Tennis 2015: Men's Final TV and Live Stream Schedule

Been here, seen this.

For the 42nd time, Roger Federer and Novak Djokovic are set to face off, this time with a U.S. Open on the line. It's hard to imagine a better conclusion for this tournament than by renewing one of the best rivalries in the game at 4 p.m. ET on ESPN and WatchESPN.

The two couldn't be much more even. Federer holds the advantage in the all-time series (21-20) and at the U.S. Open (3-2), though Djokovic has won the last two Grand Slam finals between the pair and is 7-6 in the majors against Federer.

Even the storylines have a wonderful, paralleling quality. Federer is the former top gun in the game, a graceful champion who has reinvented himself late in his career and has aged far better than most players. Djokovic is the star among stars, the player who has ascended to the top of the sport in part because he has knocked Federer off his throne in the recent Grand Slams.

Oh, and their styles clash nicely, too.

“It’s the best defensive player in the world playing the best offensive player in the world,” Paul Annacone, Federer’s former coach, told Christopher Clary of the New York Times. 

Unlike Federer and Rafael Nadal, where the rivalry was often so one-sided in favor of Nadal, the Federer-Djokovic rivalry has always been a back-and-forth affair that often becomes simply a battle of attrition. 

Federer compared his rivalry with Djokovic to the one he had with Nadal, per ATPWorldTour.com:

"

I had to adjust and change so many things playing against [Nadal], preparing against him, thinking about it when I was practising. He's probably been the guy who challenged me the most with that.

With Novak it's been more straightforward, in my opinion. That's what I like about the rivalry. I feel like he doesn't need to adjust his game as much either. I think it's just a straight shootout, and I think that's the cool thing about our rivalry. It's very athletic. We both can handle each other whatever we present to one another and I think our matches are very even.

"

Federer's game this season, however, could be argued as something not quite straightforward. The former champion has tried out a somewhat controversial new tactic, rushing the net on the second serve to quickly hit a return and surprise his opponent.

The intriguing aspect of the strategy is that, even when it doesn't work, it does seem to rattle opponents or at least cause some confusion. That tiniest psychological edge could play a huge role in a match that should be even on every front. 

He tried it against Djokovic in Cincinnati at the end of August with success while also gaining the ire of his opponent. It will be fascinating to see if Federer continues to use the technique—and perhaps more fascinating to see if Djokovic simply aims his serve directly at the onrushing Federer to send a message of his own.

Add it all up, and you have the perfect Grand Slam final. 

So yes, been here, seen this. But add one more thing...

Can't wait to see it again.
